Description

Cyclopropylbenzene is a versatile aromatic organic compound featuring a cyclopropane ring fused to a benzene ring, creating a unique structural motif with significant synthetic utility. This high-purity intermediate is valued for its role as a key building block in the synthesis of complex pharmaceutical molecules and advanced agrochemicals. It is essential for research and production in fine chemical, pharmaceutical, and agrochemical industries, where its distinct three-membered ring system is leveraged to modulate biological activity and physical properties in target compounds.

Application

• Pharmaceutical Intermediate: A crucial precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring the cyclopropyl moiety for metabolic stability or receptor binding.
• Agrochemical Synthesis: Used in the manufacture of advanced herbicides, fungicides, and insecticides, where the cyclopropyl group enhances efficacy and environmental profile.
• Liquid Crystal & OLED Materials: Serves as a core structure in the development of organic electronic materials for displays and lighting due to its rigid, planar geometry.
• Flavor & Fragrance Industry: Acts as a starting material for synthesizing specific aromatic compounds used in high-value perfumery and flavoring agents.
• Organic Synthesis & Research: A valuable reagent in academic and industrial R&D for cyclopropanation reactions and the construction of complex polycyclic frameworks.
• Polymer Modification: Employed as a specialty monomer or additive to introduce specific ring strain and aromaticity into polymer backbones, altering material properties.

Quality Control

Our Cyclopropylbenzene is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including GC, HPLC, and NMR, to ensure high chemical purity and consistency. We provide full traceability and Certificates of Analysis (COA) are available for all shipments. Our quality protocols are designed to meet the stringent requirements of cGMP and ISO standards for fine chemical production.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and ignition points. Due to its highly volatile nature, keep container tightly sealed when not in use. Recommended storage temperature is 2-8°C for long-term stability, though short-term storage at 15-25°C is acceptable.
